In 1965 Saab contracted the AJS company to build 5 prototype Saab Sonett Super Sports, the car never went into production and AJS sold off some of the prototypes. One was sold to Sigvard Sörensson (an AJS employee), who was based in Linköping he modified the car considerably and called it a Facett. In August 1966 a Facett (no engine was listed) appeared at a F3 race at Knutstorp where it failed to qualify, where the two cars related?
